Hydrostatic Drive

Constant performance and ideal adaptation to the power requirement thanks to the hydrostatic drive!

The drive system is located at the rear of the machine and is enclosed in a soundproofed housing. The hydraulic pump is flanged directly onto the drive motor, which activates the crusher via a V-belt drive. The additional hydraulics (for main conveyor, side conveyor, vibration chute, crawler gear ...) are driven via the auxiliary drives.  

The main arguments for the hydrostatic drive:

  • Hydrostatischer AntriebIndividual adaptation of the crusher speed and thus optimum adjustment of the screening curve
  • Possibility to change the direction of rotation - essential for the patented  DUPLEX System
  • Energy adjustment as needed - the hydrostatic pressure adjusts to the power requirements of the crusher, resulting in a very constant crushing performance and the diesel engine always stays within the optimum speed range
  • Thanks to the constant crushing power, the diesel consumption per tonne of production is noticeably reduced
  • Crusher overload protection: no blockages due to lack of power because of constant energy reserves
  • The conventional clutch is eliminated - no wear

Picture for illustration: 
- Variable power requirement of the crusher (kW)
- Hydrostatic pressure (bar) - pressure adapts to the power requirement
- Comparison with direct drive (clutch): lower energy support and crushing speed at high load -> increased oversize grain and possible crusher blockages
